FreeBSD amd64 randomly reboots under high load (KVM)

I'm experiencing strange behaviour with any FreeBSD 64bit running under KVM
Qemu. When machine is under high load for example compiling from ports,
after a random time it will get rebooted with no piece of information in
logs or what so ever. In this case I'm unable to get any kernel
panic/traces (kdb is enabled). On the KVM side also there are no error

This is confirmed on FreeBSD amd64 8.4; 9.0; 9.1; 9.2-RC and 10-Current.

Anyone experienced such behaviour on 64bits or mayby have a clue how can I
debug this?

With kind regards,
